Design and fitment

The Thermalright AXP90-X47 is a low-profile air cooler rated for about 95 W of sustained heat at acceptable noise. It stands 47 mm tall, which fits most mid-tower and many compact cases, and does not overhang the memory slots, so RAM height is not a concern.

Mounting kits for AM4, AM5, LGA1200, LGA1700, LGA1851 are in the box. Every current desktop socket is covered.

Which processors it suits

The Thermalright AXP90-X47 keeps 0 of the 120 processors it can mount (0 %) in the Excellent band and is a throttling risk on 96. Throttling risk begins around 88 W parts such as the Ryzen 5 5500.

In practice that makes it a good match for 65 W class processors and compact builds where height matters more than headroom.

Terms used on this page

Sustained dissipation rating
The continuous heat load, in watts, a cooler can remove at acceptable noise. This site uses realistic sustained figures rather than marketing peak numbers, and models temperature as ambient plus load ÷ rating × a per-load scale.
Thermal headroom
The cooler's sustained dissipation rating minus the CPU's boost power limit, in watts. Positive headroom lets fans run slower and quieter; 25 W or more is rated Excellent here.
RAM clearance
The tallest memory module that fits under an air cooler's front fan in its stock position. Dual-tower coolers with less than 42 mm clash with tall RGB kits (typically 44 mm) unless the fan is raised.
CPU cooler height
The installed height of an air cooler from the motherboard, compared against the case's published CPU cooler clearance. Coolers at or above 160 mm exclude many compact Micro-ATX and tempered-glass mid-towers.
